A 6.1-kg solid sphere, made of metal whose density is 2600 kg/m3, is suspended by a cord. When the sphere is immersed in a liqui
deff fn [24]

Answer:

Density of the liquid = 1470.43 kg/m³

Explanation:

Given:

Mass of solid sphere(m) = 6.1 kg

Density of the metal = 2600 kg/m³

Thus volume of the liquid :

Volume(V)=\frac{Mass(m)}{Density (\rho)}

Volume of the sphere = 6.1 kg/2600 kg/m³ = 0.002346 m³

The volume of water displaced is equal to the volume of sphere (Archimedes' principle)

Volume displaced = 0.002346 m³

Buoyant force =\rho\times gV

Where

\rho is the density of the fluid

g is the acceleration due to gravity

V is the volume displaced

The free body diagram of the sphere is shown in image.

According to image:

mg=\rho\times gV+T

Acceleration due to gravity = 9.81 ms⁻²

Tension force = 26 N

Applying in the equation to find the density of the liquid as:

6.1\times 9.81=\rho\times 9.81\times 0.002346+26

33.841=\rho\times 9.81\times 0.002346

\rho=\frac{33.841}{9.81\times 0.002346}

\rho=1470.43 kgm^3

<u>Thus, the density of the liquid = 1470.43 kg/m³</u>

2.0 mol of gas occupy 44.8 l at a temperature of 0°c. what is the pressure of the gas
MArishka [77]

The pressure of the gas is 1.0 bar.

<em>pV</em> = <em>nRT</em>

<em>T</em> = (0 + 273.15) K = 273.15 K

<em>p</em> = (<em>nRT</em>)/<em>V</em> = (2.0 mol × 0.083 14 bar·L·K⁻¹mol⁻¹ × 273.15 K)/44.8 L = 1.0 bar

How many carbon atoms are there in 45g of carbon?
nevsk [136]

Answer: 2.26x 10²⁴ atoms C

Explanation: To get the number of atoms,

First we convert mass of C to moles

45g C x 1mole C / 12 g C

= 3.75 moles C

Cancel g of C

Next convert moles of C to atoms using Avogadro's Number.

3.75 moles C x 6.022x10²³ atoms C / 1 mole C

Cancel out the units of moles C.

= 2.26x 10²⁴ atoms of C

What is an isotope like carbon-14
jek_recluse [69]
An isotope is when an element has the same number of protons and different number of neutrons. That is why the atomic mass changes.
